Since the demise of the official Google toolbar for Firefox, I've been getting a number of requests to add the "form auto-fill" and "form spell checking" features from that official toolbar to Googlebar Lite. I will not add either feature to this extension, simply because they are beyond the scope of the extension's purpose. Neither feature has anything to do with searching the web, which is the sole purpose of Googlebar Lite. If you want these two features, you need to look elsewhere.
Keep in mind that Googlebar Lite existed long before Google offered an official toolbar for Firefox. I created Googlebar Lite as a light-weight alternative to the Googlebar, not as a response to anything Google did. My primary goal with Googlebar Lite has been, and always will be, to keep it as small and bloat-free as possible. Adding features that have nothing to do with using Google's search platform only add bloat. As such, I will not be implementing them here.
